Dear all,

if understood Martin correctly, he is asking for a plot of

   Intensity vs. Angle  (can you call it circumferential profile?)

as opposed to a plot of

   Intensity vs. Distance from center (radial profile).


The plugin "Oval Profile Plot"[1] seems to provide this functionality.

Cheers,
Jan
